That is not true at all. No therapist is paid to 'serve the needs of the client'. That is not the purpose of therapy.

Therapists are paid to offer the service of therapy. Most will offer a particular type of therapy - the one that they are trained in. That may be psychoanalysis, life coaching, CBT, play therapy, Gestalt therapy or any of a whole range of other ones. They are trained in a finite range of therapeutic techniques that they will offer to clients, and most will only be comfortable working within their particular style and framework, based on their particular training.

A therapist can offer tools, and if the match is right the therapist will have the tools that respond to the needs of the client. But if the client's needs are different to the tools that are offered by the therapist, it may be necessary to accept that the match doesn't fit and find another therapist.

No therapist will respond to every need of a client. (It is actually impossible.) Clients can and should share their needs with a therapist, but any therapist worth their salt will define their boundaries and be clear about what they can and cannot do in relation to the client's needs.
Their job is not to 'serve your needs', but to encourage and support you to serve your own with the tools they have at their disposal (their training and therapeutic framework).
